Thanks for reporting this, your input is valuable!

Just to make sure: when you tried nofinal, you did pass -Dnofinal to
bison, right?  The patch installs the feature, but does not enable it
by default.

Alternatively, you can uncomment this line:

#b4_percent_define_default([[nofinal]], [[true]])

in yacc.c.

Cheers!
